(Pull Request Submitted) stat unit crashes editor

When running stat unit in the Editor, and no viewports are open, the Editor will crash.

I have created a pull request to solve the issue here:
https://github.com/EpicGames/UnrealEngine/pull/251

-	check(ViewportClient);
+	if (ViewportClient == NULL)
+	{
+		// Ignore if all Viewports are closed
+		return false;
+	}

not sure if I should “resolve” the issue until the pull-request is noticed

Hi SmilingRob,

Thank you for your pull-request. I’m going to mark this as resolved since this has been submitted for the pull-request. The developers are looking through these in the order they are received. There is no definite time-frame for this being implemented in the engine.

Thank you!

Tim
